[Intervention effects of 3000 steps more per day].

The aim of this intervention study was to evaluate the health effect of the German physical activity campaign "3000 steps more per day". Physical activity should be enhanced by means of adding 3000 steps per day to baseline level. After identifying the step counts at baseline, all participants (n = 153, 43.0 ± 8.3 years) were urged to accumulate additional 3000 steps per day to their baseline activity over a period of 15 weeks. Pre- and post-tests included measurements of (1) body weight and body mass index, (2) aerobic fitness as well as (3) subjective quality of life. At baseline the mean activity level reached 6646 ± 2305 steps per day and increased during intervention to 9886 ± 2536 steps per day. 52.9% of the participants achieved the intervention goal throughout the intervention. The body weight and body mass index reduced significantly. Aerobic fitness and subjective quality of life significantly improved. By means of the present intervention considerable health effects are achieved. Pedometer interventions are a reasonable possibility for lifestyle changes, especially for physical inactive people.
